Description

Heating mat using strain gauge {omitted}

The present invention relates to a heat-generating mat using a strain gage that controls the heat generation of a heating element according to whether or not a human body motion is detected, and forms a coating layer formed by vinyl coating a strain gauge, It is structured to improve the efficiency of the human body detection function by perfectly protecting the strain gauge constituting the strain gauge from breaking due to a large load and pressing by the gait

Generally, most of heating mat using electricity, which is heating bedding, is heated by arranging a heating line inside zigzag. If the user goes out without turning off the electric mat, the heating of the fuming line continues and power consumption continues. And various fire extinguishing mats have been devised to improve the senses of human body. First, Impedance sensing wires are used to control the heat generation according to the movement of the human body. If the object to be sensed is the whole, the production cost is high, and the volume is large, there is a disadvantage that it is cumbersome to store and move. In the case of the invention in which the second bead is embedded in the mat and the human body is sensed, It is uncomfortable and bulky and thin The mat has an inadequate range of use and third. In the case of devising to detect by the human body load due to the impact of the spring, the same height as the height of the spring is large and the same as above. Especially when the load is detected by the load of the human body, Or weighing devices, which require a leveling prerequisite for measuring weights and a robust bottom and weightable topsheet. When these devices are installed inside the mat, the thickness of the mat There is an inefficient problem that can not be overcome

This design is based on correcting these problems. Using the strain gauges with excellent human body detection, it measures the minute deformation and cuts off the power by vibration detection. Providing a heating mat using a strain gauge is a nose drop

In order to achieve the above object, the present invention relates to a thin resin film, which is formed by mixing a thin metal resistance wire and is mounted inside a mat. The thickness is very thin, It is a very useful tool for the users, as it not only disassemble, but also can be easily moved to a convenient place using double-sided tape, and the thin metal resistance line constituting the strain gauge is not broken and can be used safely for a long time

As described above, the present invention combines a metal resistance wire to a thin resin film to measure a minute deformation, so that the vibration detection function is excellent, thereby quickly detecting a situation where there is no human being on the mat, It is a resin film which is thin as a body. It is designed to be used in a comfortable state because there is no sense of heterogeneity when it is embedded in a mat.
